    Just getting started

    My question is, I purchased the Jumping into C++ book last night,
    and I go to the sample source code hello.cpp, use nano to open save, the g++ compiler code compiles, fine ex.. "g++ hello.cpp -o hello.

    No errors.
    But when I try to run by using g++ ./hello I get this >

    "./hello: In function `_start':
    (.text+0x0): multiple definition of `_start'
    /usr/lib/gcc/i686-linux-gnu/4.6.1/../../../i386-linux-gnu/crt1.o.text+0x0): first defined here
    ./hello.rodata+0x0): multiple definition of `_fp_hw'

    /usr/bin/ld: error in ./hello(.eh_frame); no .eh_frame_hdr table will be created.
    collect2: ld returned 1 exit status "

    But when I view source code in geany and compile, same no errors, when I build and run, it works.

    Question is Whats the problem?

    Thanks in advance.

    Because to RUN the program, you just type
    ./hello

    You're trying to compile it again!
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
